Abstract

In this note we establish some properties concerning non proper double points of the first and second kind of a surface in $ℙ4$, without assuming that the surface is a projection from $ℙ5$ to $ℙ4$ of an algebraic irreducible non singular surface.In particular we show that these points are not normal ones.
